Abstract

The realization of prosody varies across speakers, accents, and speech conditions. Listeners must navigate this variability to converge on consistent prosodic interpretations. We investigate whether listeners adapt to speaker-specific realization of prosody based on recent exposure and, if so, whether such adaptation is rapidly integrated with online pragmatic processing. We used the visual-world paradigm to investigate effects of prosodic cue reliability on the real-time interpretation of the construction “It looks like an X” pronounced either with (a) a H* pitch accent on the final noun, or (b) a contrastive L+H* pitch accent on looks and a rising boundary tone, a con- tour that can support a complex contrastive inference (e.g., It LOOKS like a zebra...(but it is not)). Eye-movements suggest that listeners process the L+H* on looks as an early cue to a contrastive interpretation. This effect, however, diminished when listeners had been exposed to the same speaker using the L+H* accent infelicitously. We argue that the process of prosodic interpretations is modulated by the reliability of prosodic cue values, enabling listeners to navigate variability in prosody across speakers and contexts.
